The 2026–27 student-loan interest rate for an overseas-based New Zealand borrower is 5.6% a year, calculated daily and generally added after 31 March. The borrower-status test is more nuanced than a single uninterrupted 184-day absence: a short visit to New Zealand can be counted as overseas time when the person is in New Zealand for fewer than 32 days in a 184-day period. Inland Revenue's interpretation explains the day-count tests and exceptions.
Rajeev's NZ$45,000 loan
Rajeev moves to Melbourne with a NZ$45,000 loan. The standard annual interest at an unchanged balance is NZ$2,520 (45,000×5.6%). His Australian salary does not set the standard overseas minimum repayment. IRD's loan-balance table puts a NZ$45,000–60,000 balance in the NZ$4,000-per-year band, normally split as NZ$2,000 due 30 September and NZ$2,000 by 31 March. Other relief or interest-free exceptions may apply.
An illustrative balance path
Assume NZ$45,000 at the start, 5.6% interest once per year, NZ$4,000 paid at each year-end, no fees, no further borrowing and no changes in required band. Then the next balance is 45,000×1.056−4,000=NZ$43,520, and after ten years about NZ$25,855. This is an educational simplification: IRD calculates interest daily and actual payments fall on its due dates.
When a return removes interest
IRD says a returning overseas borrower generally becomes NZ-based after 183 days in New Zealand, or enough days in a 183-day period despite absences of fewer than 32 days total. If the test is met, interest from the return date is written off retrospectively. It does not stop permanently on arrival or require 184 consecutive days back in every case.
